Optimal Gevrey Regularity for Supercritical Quasi-Geostrophic Equations

Communications in Mathematical Physics
AbstractWe consider the two dimensional surface quasi-geostrophic equations with super-critical dissipation. For large initial data in critical Sobolev and Besov spaces, we prove optimal Gevrey regularity endowed with the same decay exponent as the linear part.

Analytical smoothing effect of solution for the boussinesq equations

, 2017
In this paper, we study the analytical smoothing effect of Cauchy problem for the incompressible Boussinesq equations. Precisely, we use the Fourier method to prove that the Sobolev H 1-solution to the incompressible Boussinesq equations in periodic ...

Derivative loss for Kirchhoff equations with non-Lipschitz nonlinear term

, 2009
In this paper we consider the Cauchy boundary value problem for the abstract Kirchhoff equation with a continuous nonlinearity m : [0,+\infty) --> [0,+\infty).

On nonlinear Landau damping and Gevrey regularity

Nonlinear Analysis
In this article we study the problem of nonlinear Landau damping for the Vlasov-Poisson equations on the torus. As our main result we show that for perturbations initially of size $ε>0$ and time intervals $(0,ε^{-N})$ one obtains nonlinear stability in regularity classes larger than Gevrey $3$, uniformly in $ε$.
